And, if there are lions still carrying its genes, can genetic fingerprinting (or should that be "pawprinting"?) be used to bring these beautiful big cats back from the brink of oblivion?

Kay Hill, founder of the conservation charity Wildlink International, based in Essex, England, says she has "high hopes" that genetic testing currently being carried out on lions and lion tissue in several European countries will "result in a major breakthrough."

"It is a very exciting project," says Ms. Hill. "Barbaries are such wonderful animals.

"Whenever people think of a lion, they think of a Barbary.... But it is important to carry out precise research ahead of a breeding program. Many believe any lion with a black mane and dark chest hair is a Barbary. That isn't true. Only DNA testing can prove the lineage of a Barbary."

New additions to a noble line

Saffi's father is Kabir, known to descend from the Barbary lions owned by the king of Morocco when the last known Barbary in the wild was shot in the 1920s. Her mother is Jade, whose pedigree runs from the same source.

Both lions are held at Port Lympne Zoo, in Kent, where Saffi was born last July. In a further sign of success, two more cubs, as yet unnamed, were born to the pair early this year.

A full-grown male Barbary lion is said by historians to have weighed more than 500 pounds, compared with less than 400 pounds for today's male African lion. A Barbary could measure 10 feet from its ears to the tip of its tail. It reached Rome from North Africa more than 2,000 years ago.

"It is probable that the Romans used Barbary lions in their gladiatorial contests," says Hill. "The authorities in the Italian capital have granted us permission to take bone samples from skeletons in dungeons underneath the Colosseum. That will happen in a few weeks.

"We are also taking powdered bone samples from known Barbary-lion skeletons in museums in Italy, France, and Belgium, and subjecting them to DNA testing at Oxford University. Then we'll take hair samples from Saffi and her parents, and see whether we get genetic matches," Hill says.

"We're looking for the closest possible DNA match. We hope Saffi will provide the start point for selectively breeding the Barbary lion back into existence," she adds.

A fabled past

Panthera leo leo, as the breed is known formally in Latin, is famous in legend and history.

In Aesop's fables, it would have been a Barbary lion that spared Androcles in the arena, out of gratitude to the Greek slave who earlier removed a thorn from his paw.

Julius Caesar once put 400 of the animals on show. His rival Pompey went one better with 600.

In Ethiopia this century, the Emperor Haile Selassie tethered Barbary lions near his throne.

A Barbary was used as a model for the bronze lions seen today in London's Trafalgar Square.

Most recently, the menacing Scar in Disney's "Lion King" was patterned on a Barbary. Hill has "serious doubts," however, about whether the lion that roars before every MGM movie is a Barbary. "But we're checking it out," she says.

Barbaries, also known asNubian lions, used to prowl widely in North Africa, which was then forested terrain. But by 1700, the last wild Barbary in Libya had been killed by farmers concerned about the threat to livestock.

By 1800, the species was extinct in Egypt. Only in Morocco did it continue to survive in remote areas. Eventually the last known Barbaries became captives in the royal collection in Rabat, the capital.

"Through genetic fingerprinting we hope to identify and selectively breed lions which carry Barbary genes," says Nobuyuki Yamaguchi, an animal ecologist at Oxford University's Wildlife Conservation Unit, where the DNA testing will be done. "I think we could reach our goal in a couple of generations."

If all goes well, says Dr. Yamaguchi, the next step will be to release specially bred lions on a site in Morocco's Atlas Mountains. Wildlink's Hill has already made arrangements for that to happen. Two years ago, she persuaded the Moroccan government to set aside some 250,000 acres in the mountain range for Barbary lions to roam.

"We need to plant vegetation and introduce a food source," says Hill. Arrangements are being made to provide the lions with natural prey, such as red deer.

Morocco is keen to restore the Barbary lion's lineage.

"It is our ideal to see the Barbary lion back in the wild," says Brahim Haddane, curator of Morocco's Rabat Zoo, which houses the king's collection of about two-dozen animals. "I have been working for this for the last 20 years."

Two decades ago, a team of German scientists also tried to breed Barbaries, but failed.

Hill believes success this time is vital. "If we fail, another part of our untamed past will live only as a symbol, a myth, and a memory," she says.
